The Democrats are the party the nation has always turned to when times are tough and people are still hurting, Democratic National Committee Chairman Tim Kaine said Wednesday in a speech intended to sharpen the Democrats message in the final two months before the November election.

Most polls and pundits predict a Republican victory this fall with the GOP taking the majority in the House and maybe the Senate. But Kaine basically told an audience at University of Pennsylvania to bring it on.

"We have always been the underdog party and we always will be, speaking for regular everyday people throughout this great country," Kaine said. "We love a tough battle because the nation is counting on us at a challenging time and we know that, while change is never easy, we can’t make progress without fighting for it."

Introducing Kaine was Gov. Ed Rendell, who is always good for a fun soundbite. He warned against turning the country over to Republicans, who he said, have been taken over by "wackos."

"They’re nuts, they are flat out crazy," Rendell said. "Even if a candidate in a district isn't particularly crazy himself, isn't a fruit loop, we’re going to turn over the Congress to a party that’s controlled by the wacko wing?"
